- In BGM theme the almost invisible cross when the mouse is not over it is a skinning choice, but you can easily replace it by a more standard cross, for this :
create a copy of the file named titlebar_X_2_mouseover.tga located in the folder JRR Skins collection\# BGM #\opaque\
Then rename the copied file as titlebar_X_2.tga and then replace the original titlebar_X_2.tga file with it and you're done.

- In Monster Lair theme folder, the file center_silver.tga is located in "basebox" folder.
Border files names also contains the words upper/lower/side.
you can, for example replace center_silver.tga by the one from BGM opaque located there :JRR Skins collection\# BGM #\opaque\base_box_center_silver.tga.
copy it, rename it center_silver.tga and replace the file in JRR Skins collection\# Monsters Lair #\basebox
You're done. The borders of the panel will remain a bit translucent but the center will be perfectly opaque.

I had basically the same question as Myrthian but with regards to the Monsters Lair skin. I too would like a solid black background for all my windows as the translucent type causes some difficulty for me as I have vision issues. I've tried the B.G.M. "Opaque" but the issue with that is the 'x' to close windows becomes almost invisible for me unless I mouse over it.

If you could point me to the right files I would need to modify I would greatly appreciate it.

- JRR Erebor theme is no more an addon and is now a part of the main JRR pack, porting to 28 the number of themes and variations included in the main pack !
If you had the Erebor theme previously installed, please delete its old installation folder to avoid conflict with the new one.
- Delving Hills theme have now a third toolbar profile.
- Based on the Update 22 skinning pack, many icons are recolored (no more blue based).
- A few portraits have been enhanced.
- 2 loading screens have been changed.
- A few enhancements in Monsters Lair theme.
- Some other changes and enhancements here and there.

@ Myrthian
Hi and sorry for the late answer, I didn't saw your question before.
The files you need to edit to change the background color are located in the sub folder of delving hills named "silver".
the center of the background and its borders are separate files.
the center is named center_silver.tga
The borders are upper/lower/side/bottom beginning files.

Hi, and you're welcome.
Lotro is able to find the skins folders locations, no matter the depth of the tree path, same thing for the name of the folder(s) containing the skins.
Nevertheless, optional skin addons like "greyskin" or "smallbar" won't work correctly is the tree pathing and naming aren't exact.

I had trouble getting them to work at first. I had to copy the files from the JRR skins folder up one level into the skins folder itself, then it worked fine. I just wanted to let you know in case some others had a bit of trouble getting it to work.

I also found I had to scroll way down in my UI options to find the option in game to change the skins.

Beautiful work and thank you for keeping up with this. I've just come back to the game after a long time, and it's nice to see all these interface plug ins and skins.

Lotro update 21.2 introduced 2 new filter buttons on the quest log panel.
This JRR skins pack update consists only in a hotfix and a re-balancing of this panel to relocate the new buttons at the bottom of the panel.

A special big thank to Siloren (software engineer in Standing Stones Games) for working and communicating about the panel code entries which made this fix possible.
Of course thanks too to Andvarion, ScottK and Osdor for informing about this issue and about the solution offered by Siloren.

I cannot move the new buttons on the quest log panel without knowing their source code, and unfortunately I would need a skinning update pack from turbine for that. The last one has been published for Lotro update 20.

That said, you can manually disable/remove the extended quest log panel customization by editing (with Windows Notepad or any else text editor) the skindefinition.xml file of the theme you want to fix (in the sub folders of JRR skins collection. (there is 1 skindefinition.xml file per skin).
To disable the panel, simply delete all the code between the lines :
